Apache
Apache is a widely-used open-source web server software that serves web content over the internet. It is developed and maintained by the Apache Software Foundation and supports various operating systems, including Unix, Linux, and Windows. Apache is known for its modular architecture, allowing extensions through modules for features like security, caching, and scripting languages.
Developers should learn Apache when building and deploying web applications, as it is essential for hosting websites and handling HTTP requests. It is particularly useful in LAMP (Linux, Apache, MySQL, PHP) stacks for dynamic web development and in enterprise environments due to its stability and extensive documentation. Use cases include serving static files, proxying requests, and integrating with backend technologies like PHP or Python.
